In terms of technical prowess and soundness, Leon is excellent. Beautiful footwork, good timing, good defense, untelegraphed punches, good kicks, stellar elbows from the clinch. Nobody moves like him at WW. Seriously, don't be sleeping on Leon and go watch his fights. He may not be the most dangerous striker in terms of KO, but technically, nobody comes close. Mas is a good striker, too, yes I concede that, but he is a much heavier on his feet, older dude. Leon is just on another level.
Wonderboy? Ok, I can accept that but it is such a special style that it kind of falls outside of conventional benchmarking.
Wait did I just read that you just wrote that Colby has better striking than Leon? Buddy please you just lost all your credibility with that one. Please tell me that this was hyperbolic.
Oh and off-topic but please, also re-watch the Felder fight and you will see clearly that "Felder winning the standup against RDA" is utter, manufactured horseshit. It is simply not true. Felder's timing, distance and reflexes was COMPLETELY OFF the whole fight. He was getting tagged with jabs and straights literally the whole fight and looked like he did not even belong in there.
